Hello ! After "solving" our problem with the 386 33-Mhz motherboard (ISC 2.2 wouldn't boot on it - we changed it against a 486 motherboard and it works) we are running in a problem again. However, this time it is rather an annoying "feature" than a big problem. We bought the STB Power Graph board and an EIZO (Nanao) 9070-S monitor. (16-inch 1024x768 non-interlaced). All the normal VGA modes are working well. However, if we are using the Xserver which came with our ISC 2.2 (Interactive UNIX), black (on white background) or white (on black background) are remaining on the screen, whenever we move the window. If we use a program, e.g., xhpgl, and we request to redraw the window, these pixel will go away. What is the problem ? If that is a problem with the board we will send it back immediately. We have other problems with our dealer in Switzerland. We got the board at the beginning of Dec. 1990 without MANUAL and driver disk. I requested that from the dealer on 14-Dec-1990 and again on 23-Jan-1991. Although, he said "we will ship it immediately", nothing arrived, yet. I called again today (1-Feb-91) and he said I will get a COPY OF THE MANUAL ? Are they short in manuals ??? Now, that we have a DOS partition on our system, we want to use Windows 3.0 with that board but can't use the higher resolution modes :-( Even some other DOS program like Cshow, Vpic, etc. which have drivers for the Tseng Labs ET-4000 chipset (and even for the STB 4000) don't work with this board in the 256 colour modes (no, not even 320x200 !). Thank you for your help, Norbert Bladt. -- Norbert Bladt, Ascom Autelca AG, Worbstr. 201, CH-3073 Guemligen, Switzerland Phone: +41 31 52 92 14 Mail: nbladt@autelca.ascom.ch UUCP: ..!uunet!mcsun!chx400!hslrswi!aut!nbladt

We had the same problem here. As it turned out the cause was ANOTHER board in the system causing interference with the POWERGRAPH. In our case it was a HAYES JT Fax board. No matter how we set it up, we would end up with random pixels on our X11 root. We ended up replaceing the fax board with another companies version and all problems stopped. This happened with 3 seperate systems. I feel that there is some questionably designed circuits on the STB board that picked up noise from the fax board. We would have replaced the STB, but there is really no other VGA adapter for ISC (in the VGA relm) that gives 1024x768x256 for a affordable price. We eventually replaced all of the VGA boards with MFG (Microfield) V8 boards (1024x1280x256 out of 4096), but this is WAY out of the relm of the casual home or small business user.
